Pats defense has given up 170 Points this season or 18.8 PPG.
There are currently just 7 teams ahead of them. Buffalo (118PA) , Pittsburgh (142PA) , Denver (153PA - 17), New Orleans (155PA) , Arizona (138 PA), LA Rams (168 PA), and Seattle (169 PA). However, Buffalo (14.75PPG) ,NOLA (19.375), Arizona (17.25PPG) , LA Rams (21), and Seattle (21.125) have all played 1 fewer game than the Pats and Pittsburgh (20.285 PPG) has played 2 Fewer..
I think that the Pats defense has been very underrated despite the Dallas and New Orleans games
